Enabling or Installing D-Link DWM 156 in 12.04 LTS?

view story

http://askubuntu.com – No support for this USB broadband modem. Does anyone have a clue on how to enable or install it in Ubuntu 12.04? The device is listed by lsusb as 2001:a80b but in network manager, there is nothing in there. Device is detected in /dev/sr1 or sr2 and can be mounted with #mount /dev/sr1 or sr2 /media/<mkdir your own directory> It contains various files. A file named "dlinkusbmodem.deb" is present. Double clicking opens it in Software Center but gives error during installation. Figures it is a 32-bit driver for 32-bit OS. Please help. (HowTos)
